Do you have any questions?

The testo 625 thermohygrometer comes into its own in all situations where the right indoor climate is crucial, for example in archives, storerooms, greeenhouses and buildings. The testo 625 also calculates the dew point and wet bulb temperature quickly and accurately.

The testo 606-2 moisture meter allows you to measure the moisture content in wood and building materials – and the surrounding environment too. This means that you are now also able to check storage and drying conditions quickly and easily.

The compact testo 605i temperature and humidity measuring instrument with bendable probe head features professional measuring technology in an intelligent format: it can be used in conjunction with a smartphone/tablet and the testo Smart Probes App to reliably measure air temperature and humidity in rooms and ducts.

The testo 622 thermo hygrometer and barometer is designed to provide you with an at-a-glance look at the air temperature, relative humidity and air pressure. Ideal for monitoring the ambient air, especially in laboratories during calibration or when running experimental setups.

The testo 635-1 temperature and humidity measuring instrument enables you to measure the temperature, air humidity and dew point – in compressed air as well. State-of-the-art technology and a large selection of probes, which are available as an option, enable this wide variety of measuring possibilities.

Probes available as an option mean you can measure air humidity, temperature, absolute pressure and dew point in compressed air

The elegantly designed testo 623 thermohygrometer provides you with a quick and convenient means of measuring the temperature and humidity in offices, living spaces and commercial premises and logs the readings over a period of 90 days.

Measures the temperature and humidity in the room and alerts the room’s occupants when thresholds are reached

Large, easy-to-read display: shows the current reading and provides you with an at-a-glance 90-day statistic snapshot

Non-contact temperature and moisture measurements – with only one device. The testo 835-H1 infrared thermometer not only measures the temperature but has an intergrated moisture sensor that allows you to measure moisture too.

Measure temperature, moisture and dew point with only one device

Easy and comfortable to use: easy-to-follow menu guide, can save up to 200 readings, data analysis with free-to-download software

Four-Point-Laser and 50:1 Optics for precise measurements even over long distances

For air-conditioning engineers: Compact kit containing four measuring instruments for your most important measuring tasks in, on and involving air conditioning systems. The testo Smart Probes App enables you to work more easily and efficiently: Use intuitive measurement menus for volume flow measurement, for automatic calculation of the dew point and wet bulb temperature or for detecting areas susceptible to mould according to the traffic light principle. Measurement data reports can be emailed directly as a PDF or Excel file.
